Morgan suffered broken ribs, a broken nose and a broken leg in the crash early in the morning of Saturday, June 7, while his friend and comedian colleague James McNair was killed.

Morgan was a regular on Saturday Night Live for seven years and later starred in the series 30 Rock, for which he was nominated for an Emmy.

The suit, filed Thursday in the U.S. District Court in New Jersey, blames Morgan's injuries on Walmart driver Kevin Roper's "negligence." Roper was almost at a his drive time limit, according to a preliminary report by the National Transportation Safety Board.

Walmart responded with a contrite statement. "This has been a terrible tragedy. We wish Mr. Morgan, Mr. Fuqua Jr., and Mr. Millea full recoveries," Walmart said, NBC reports. "Our thoughts continue to go out to them, their families and friends, as well as to the families and friends of everyone involved, including Mr. McNair who lost his life. We are deeply sorry that one of our trucks was involved.

"As we've said, we're cooperating fully in the ongoing investigation," Walmart went on. "We know it will take some time to resolve all of the remaining issues as a result of the accident, but we're committed to doing the right thing for all involved."
